It (Ilairns. (Cl. ZZZ-4:26)

The present invention relates generally to dispenser devices adapted forcontrolled dispensing of preparations in liquid or paste form such asmay be put up and shipped to the trade in small containers, and moreparticularly to improvements therein.

Heretofore, various dispenser devices have been proposed for efiectingcontrolled ejection of predetermined quantities of liquid or pastepreparations as exemplified in the disclosure of the device of theLippman Patent No. 2,700,490 issued January 25, 1955 wherein a wormelement in threaded engagement with a vertically movable piston may bepositioned in a replaceable can container and used for applying adesired degree of pressure to the contents thereof. Progressive rotationof the worm element in engagement with the pressure applying piston isnormally accomplished by a ratchet mechanism provided in a base supportmember having means arranged for opening a valved orifice incommunication with the interior of the container simultaneously withapplications of predetermined pressures on the contents thereof. Thus,measured quantities of the contents of a replaceable container may bedispensed in a convenient manner. However, dispenser arrangementsof theprior art have had the disadvantages of being subject to frequentfailures in service causing high maintenance costs and in theirembodiment of valve orifice closure means permitting untidy dripping ofthe contents therefrom.

Accordingly, a primary object of the present invention is to provide animproved dispenser device of the aforesaid type for effecting controlledejection of measured quantities of liquid or paste preparations.

A further object of the present invention is to provide improvedself-closing valve means in a dispenser device of: the aforesaid type,the valve means being constructed and arranged to be easily actuatedinto open position simultaneously with an increase in pressure on thecontents of the dispenser whereby predetermined amounts of the liquid orpaste contents will be progressively ejected as required.

A still further object of the present invention will be to provide animproved dispenser device of the aforesaid type embodying improved meansfor holding a replaceable container in mounted position therein andthereby eliminating the need for externally applied clamping pressureson unsupported portions of the container that may cause deformation ofportions thereof so as to interfere with successful operation of devicesof this character.

Still another object of the present invention is to provide in animproved dispenser device of the aforesaid type, an improved clutchmechanism arranged in cooperation with a worm element of the device foreffecting uni-directional turning thereof to cause predetermineddownward movement of a pressure-applying piston'provided in threadedengagement therewith in response to strokes of a handle means arrangedto extend externally of the dispenser device, said clutch mechanism alsobeing in operative connection to an improved valve means of the presentinvention, whereby predetermined quantities I 2 of the containercontents will be intermittently extruded through the valve orifice uponmanual actuation of said handle.

Still another object of the present invention is to pro vide an improveddispenser device of the aforesaid type wherein the various'parts thereofwill be interconnected in a novel manner to form a unit which will beadapted for long service under even adverse conditions of use with verylow maintenance costs.

A still further object of the present invention is to provide animproved soap dispenser of the aforesaid type which will be readilysusceptible to manufacture by modern mass production techniques at lowunit cost.

Further objects and advantages of the present invention will appear inthe specification set forth hereinafter.

In the drawing:

Fig.4 is a fragmentary elevational view partly in section taken alongthe line IV IV of Fig. 2; and,

Fig. 5 is a fragmentary elevational view partly in see- I tion showing amodification of the present invention.

Referring more particularly to the drawings, the device according to thepresent invention as illustrated in Fig. 1 comprises generally acontainer ltl, a wall-mounted base casting 12, an upright post member 14fixedly mounted to said base casting 12 so as to extend centrallythrough the container 10, a one-way clutch mechanism lti'a rotatablethreaded worm element 18, a worm retaining knob 20 threaded onto theupper end of the center post 114, and a valve mechanism 22 operablyconnected to the oneway clutch mechanism 16 through the medium ofpivotally interconnected links 24 and 26.

The base casting 12 will be cast preferably of a suitable metal such asaluminum, or the like, into a generally hollow circular configuration asshown in Figs. 1, 2, and 4 to provide a recessed annular upwardlypresented seat portion 3% at its upper end which extends downwardly fromthe inner edge thereof to form an inner Well portion 32 at the bottom ofwhich will be formed a circular upstanding boss portion 34. As shown inFigs. 1 and 2, the casting 12 may be provided with an integral bracketpart 36 supported by means of an integral rib portion 33 and providingflat faces ill arranged to be mounted against a supporting wallstructure through the medium of suitable bolt or other fastener meanswhich may be passed through openings 42-4 either directly thereto orthrough the medium of any suitable mounting bracket arranged as would bereadily apparent to a person skilled in the art. Thus, it will beappreciated that a dispenser made according to the present invention maybe permanently aflixed to a supporting Wall structure, if desired, ormay be accommodated easily for connection to a suitably arranged bracketmeans where-by the dispenser device may be removably clamped thereto.

The container 10 preferably will be formed of a sheet material into agenerally cylindrical shape and will be utilized for shipping liquid orpaste preparations to the trade for use as part of a dispenser devicemade in accordance with the teaching of the present invention in themanner more specifically set forth hereinafter. The bottom of thecylindrical container 19 normally will be provided with a cappedcircular opening 46 while the open upper end thereof will be arranged tobe closed by means of a removable cover member 43 having a centralaperture 50 therein normally closed with a suitably formed removablefriction cap of any suitable type (not shown) as may be required toretain the contents of the container prior to its installation for usein the dispenser. It will be appreciated that the bottom wall portion 52of the container and the shape of the cover member 48 (Fig. 1) may beformed in various configurations whereby containers 10 may be stacked insuperposed position to facilitate storage thereof, or the like, withoutthese modified forms of container covers in any way interfering withoperation of the dispenser device according to the present invention inrelation therewith. It will further be appreciated that the opening 50in the cover member 48 will be formed of a diameter only slightly largerthan the external diameter of the center post knob 20 so as to beadapted to clear the outer surface of the latter but still providing aneffective shield against the ingress of foreign particles and dust intothe interior of the container such as might contaminate the contentstherein. The base portion 52 (Fig. 1) of the container 10 will beadapted to seat onto a sealing gasket 54 adhesively attached to thesurface of the upstanding peripheral seat 30 of the hollow casting 12,and thereby will seat the bottom of the container when in mountedposition against the passage of air into contact with the contents. Theboss portion 34 of the casting 12 will be provided with a centrallylocated threaded opening 56 through which the lower threaded end portion58 of the center post member 14 will be screwed in order that the centerpost 14 will be positioned in axially aligned relation with thecylindrical container 10 (Fig. l). A nut 60 may be threaded onto theprotruding end 58 of the center post 14 to further rigidly hold thecenter post in upright position without placing undue stress on theinternal threads provided in the central opening 56 of the boss 34.

The externally threaded worm element 18 will be slip fitted over thecenter post 14 so as to be freely rotatable thereon. As shown in Figs.l, 2 and 3, the lower end of the threaded worm element 18 will beprovided with a pair of diametrically opposed integral lug portions 62-62 which will be suitably dimensioned to freely fit into diametricallyopposed recesses 64-64 formed in the clutch part 66 of the clutchmechanism 16. When in engaged position in the clutch part 66, theopposite end of the worm element 18 preferably will extend upwardly toslightly below an annular shoulder 68 of the center post 14 to providesuflicient clearance for permitting rotation of the worm element belowthe lower abutment face of the knob 20 which will be threaded onto theupper end 70 of the center post 14 into abutment with the shoulder 68.

A movable piston element 72 will be provided in threaded engagement withthe rotatable worm element 18, as shown in Fig. 1, so that rotation ofthe worm element 18 through the medium of the one way clutch mechanism16 and the parts associated therewith will apply predetermined pressureon the container contents 74 which will be trapped between the undersideof the piston and the base casting 12.

An important feature of the present invention is that the rotatable wormelement 18 and the piston element 72 will be retained against axialmovement relative to the center post 14 by abutment of the upper end ofthe worm element against the knob 20 screwed on the upper end of thecenter post, with the result that the pressure applied to the contents'74 will be transmitted therethrough to act on the upper surface of thecontainer base portion 52 and thereby retain the container ineffectively clamped relation on the gasket 54 of the upwardly presentedseat 30 of the casting 12, and thereby eliminate the need for anyexternally applied clamping pressure on the walls of the container 10which might cause deformation thereof and result in an inoperablecondition.

In the embodiment of the invention shown in Fig. l, the piston element72 is comprised of a pair of opposed annu lar parts 74-76 whichpreferably will be spot welded together as shown for example at 78-80.Centrally located between the inner ends of the annular elements 74-76there will be provided an internally threaded annular element 82integrally connected therewith by means of the spot welds 8486 and beingin threaded engagement with the rotatable worm element 18. In order thatrotation of the worm element 18 will result in axial movement of thepiston element 72 therealong, the external periphery of the pistonelement is arranged to be provided with an annular resilient gasketmember 88 in fixed relation therewith and of slightly greater externaldiameter than the inside diameter of the container 10. Thus, it will beappreciated that insertion of the piston element 72 into the inside ofthe container 10 will necessitate compression of the resilientperipheral gasket 86 which thereafter will exert suflicient radial forceagainst the container walls to prevent its rotation in the process ofbeing carried downwardly by the action of the worm element 18 to applythe desired pressure on the paste contents. A suitable wire bale member88 may be pivotally mounted on the upper surface of the piston element72 to facilitate handling thereof as during removal and mounting of thecontainer in the dispenser unit (Fig. 1).

Uni-directional rotation of the worm element 18 will be accomplished, asshown in Figs. 1, 2, 3 and 4, through the medium of the one-way clutchmechanism 16. This clutch mechanism, in the form illustrated in thedrawing, includes an outer annular ring 89 mounted for movement on anupwardly presented annular seat 90 formed by the bottom of a recess 92of the upper portion of the well 32 in the bottom of the casting 12 inoperative connection with the annular inner clutch part 66, the latterbeing rotatably mounted on the reduced diameter portion 94 of the centerpost 14 as shown in Fig. l and being retainedagainst axial displacementby engagement of the upper surface thereof against the annular shoulder95 provided on the center post 14. As shown most clearly in Fig. 3, theclutch part 66 is provided on its periphery with a plurality of evenlyspaced generally V-shaped teeth 96, these teeth having straight radiallyoutwardly extending lands on one side and inclined faces on theiropposite sides whereby contact of the latter with spring-pressed pawlmembers, as noted below, around the periphery of the teeth 96 will causethese inclined faces to yieldingly press these pawls outwardly with norestriction on rotatable movement while reverse movement of these pawlswill cause rotation of the clutch part 66 and the worm element connectedthereto around the center post 14. In order to facilitateuni-directional movements of the clutch, the bottom edge of the clutchpart 66 likewise will be provided with a plurality of generally V-shapedteeth, each having beveled and fiat faces corresponding to each of thefaces of the ratchet teeth 96 on the outer periphery of the part 66.Thus, it will be appreciated that the ratchet teeth on the clutch part66 will be arranged to permit either clockwise or counterclockwiserotation thereof about the center post 14 as may be desired, and thatthe formation of the beveled teeth on the bottom of the clutch partcorresponding to the peripherally located teeth will be used incooperation with a suitable springpressed detent as describedhereinafter to prevent rotation of the clutch part 66 in other than onedirection about the center post 14.

In the embodiment of the invention illustrated in Figs. 1, 2, 3 and 4,the outer annular ring 89 of the clutch mechanism 16 is provided with apair of diametrically opposed pawl members 104104 arranged to bepivotally mounted therein adjacent the inner edge thereof. The outerends of these pawl members cooperate with a pair of compression springs106-406 fitted in suitably provided recesses 107107 provided in the ring89 in order to resiliently urge these pawl members into engagement withthe peripherally spaced teeth 96 of the inner clutch part 66. For thepurpose of preventing reverse rotation of the clutch part 66, there isprovided a detent member 108 which is slip-fitted into an opening in thetop of the central boss portion 34 of the casting 12 at a suitableposition therein and is arranged to be resiliently urged upwardly intoengagement with the beveled teeth 102 provided on the bottom of theclutch part 66 by means of a compression spring 110.

The annular ring 89 will be rotated within certain predetermined limitsby means of a lever member 112 fixed in the inner end of a rotatableshaft member 114 journaled through the base of the casting 12 in aradially outwardly extending position for connection at its outer end toa suitably formed handle portion 116 as shown in Figs. 2 and 4. Thelever 112 will be fixed in the inner end of the shaft portion 114 sothat its lower end portion will extend downwardly between a pair ofspaced upstanding shoulder portions 118-118 provided in the base portionof the casting 12 for the purpose of limiting the range of pivotalmovement of the lever 112 and thereby the handle member 116. The lever112 and the handle 116 may be resiliently urged to one end limit oftheir movement by means of a clock-spring 1211 (Figs. 2 and 4) arrangedaround the shaft part 114 with its inner end fitted into a slot 122 inthe inner end of the shaft part 114 while its outer end may be supportedon the upper edge of an upstanding wall portion 126 in the casting 12.Thus, it will be appreciated that the shoulders 118-118 of the casting12 will be suitably spaced in order that one stroke of the handle 116will cause the lever member 112 to engage the outer annular clutch part89 and rotate the samethrough a range of rotary movement, clockwise inthe view shown in Fig. 2, so as to cause the pawls Hid-11M carriedthereby to engage the fiat faces of the peripheral teeth 26 on the innerclutch part 66 and rotate the latter about the center post 14 by anamount equivalent to the spacing between the adjacent flat parts of theadjacent ratchet teeth $6. It will be appreciated that this will causerotation of the worm element 18 by a corresponding amount with resultantapplication of predetermined pressures on the contents of the containeras noted heretofore. Return movement of the lever 112 and the handle 116under the urge of the clock-spring 120 will bring the annular clutchelement 89 back to its original position into condition for furtheroperation of the unit since it will be appreciated that reverse rotationof the clutch part as will be precluded by engagement of thespring-pressed detent 1138 with the flat faces at one side of thebeveled teeth 1112 provided on the underside of the clutch part 66.

Therefore, it will be appreciated that embodiment of the presentinvention in a dispenser device of the type proposed having its variousmechanical parts designed to provide the desired predetermined pressurefound to be most satisfactory for ejection of the contents of thecontainer will result in maintenance of uniformity in the amount of suchpressure exerted on such contents at each stroke of the handle 116 toprovide efiicient and uniform discharge of the contents from thedispenser.

In order to permit extrusion of predetermined amounts, for example, of apaste-type soap from the contents of the container 10, the valve means22 will be arranged to be operable in synchronism with manual operationof the dispenser handle 116 as shown for example in Figs. 1, 2 and 4-.Thus, the casting 12 will be provided with an extrusion orifice 13%having its inner end in communication with the interior of the container14) and through which the contents of the container may be dispensed incontrolled amounts as determined by the operation of the valve parts inthe below described manner. The inner ends of the extrusion orifice 136will be formed of reduced diameter in order to provide an annular springseat 132 therein against which will be seated a compression spring 134-for resiliently urging a ball type closure valve 136 integrally fixed onthe outer end of the valve link 24 into seating relation against theinner valve seat opening 138 in the inner end of a valve insert 1 0pressfitted into the outer end of the extrusion orifice 130, thiselement 72 insert being provided with an orifice 142 through which thecontents of the container will be dispensed into the hand of a user. Byvirtue of the position of the valve seat 138 being in close proximity tothe discharge orifice 142 of the valve means as in the arrangement shownin Figs. 1, 2 and 4, a substantially dripless discharge of the containercontents will be achieved.

It will be appreciated to be a still further feature of the presentinvention that the compression spring 134 is preloaded inthe process ofassembly. The innermost end of the link member 26 is pivotally securedin a suitably located opening 14-4 of the rotatable outer annular clutchpart 89 for rotation thereof by manual actuation of the handle member116 to simultaneously open the ball-bearing valve part 136 so as toeject predetermined quantities of the pressurized contents of thecontainer 10 through the discharge orifice 142 simultaneously withapplication of pressure by the worm-operated piston element '72.

An important function of the valve 22 in the present device in thatrelease of the handle 116 permits the ball part 126 to be spring-urgedtoward the valve seat 138 to push the paste contents before it outwardlythrough the valve orifice 130 to create a pressure relieving conditionrearwardlythereof. This feature eliminates the build up of excesspressures in the dispenser such as have heretofore resulted in splittingthe seams of the container 11) as in prior art applications.Furthermore, control will be maintained over the rate of discharge ofthe pressurized contents of the container 10 by varying the size andspacing of the coils of the preloaded spring 134 as may be desired sothat it will perform the dual function of maintaining the ball valvepart 136 in seated position on the valve seat 138 and restricting therate at which the contents may be discharged through the extrusionorifice. It will be appreciated further that the function of thecompression spring 134 in closing the valve 22, will assist in returningthe rotatable outer annular clutch part 89 to its original inoperativeposition and thereby will complement the action of the clockspring 124in returning the handle member 116 back to its initial position. Thisarrangement will obviously serve to balance the forces applied on theclutch part 89 as at substantially diametrically opposed points thereonso as to provide a smoothly operable mechanism giving long lastingtrouble-free operation. Of course, it will also be appreciated that thecompression spring 134 might be designed readily so that its valveclosing function might also cause the rotatable clutch part 89 and thehandle 116 connected therewith to return to their original position soas to thereby eliminate the need for a clock spring member 12G as shownin the present embodiment of the invention.

The lower portion of the worm element 18 will preferably be relieved orunthreaded to receive the piston freely at the end of its stroke inorder to avoid continuous screw pressure against the base of thecontainer such as might damage the dispenser.

For a cycle of operation of the improved dispenser device illustrated inthe drawing, it is only necessary for the operator standing in front ofthe machine to turn the handle member 116 substantially a quarter turnforwardly with one hand while cupping the other hand under the valvemeans orifice 142, and then releasing the handle immediately upon thesame reaching the limit of its movement, that is, by the lower portionof the lever member 112 engaging one of the shoulders 118 of the casting12 (see Fig. 4-), thereby allowing the clock spring 121) and thepreloaded compression spring 134 to return the valving and clutch partsto the normal positions thereof. This forward movement of the handleeffects rearward swinging full line position thereof to the dotted lineposition thereof as shown in Figs. 1 and 2. Simultaneously with openingof the ball bearing valve 136, the clutch part 66 will be actuated byengagement of its peripherally arranged clutch teeth with theresiliently pressed pawl members 104 104 pivotally mounted on the innerportions of the rotatable clutch part 89, and by consequent rotation ofthe threaded worm element 18 connected to the clutch part 66, a slightdownward movement is transmitted to the non-rotatable piston element 72.This slight downward movement of the piston element 72 will besufiicient to pressurize the contents of the container 10 and to eject apredeterminedly small amount of the contents into the cupped hand of theoperator. Because the one way clutch mechanism 16 is arranged to beeffective only in the forward direction of operation, the threaded wormelement 18 is turned in pressure-applying direction only, and hence,repeated operation of the dispenser is effected to move the pistonreadily downward until it reaches the unthreaded portion at the bottomof the worm element.

When the container 10 is empty it is only necessary to remove the emptycontainer and then the piston element 72, replacing the empty containerwith a full one from which the covers have been removed from both ends,replacing the piston on the sleeve, removing the small cap (not shown)centrally located in the cover member 48 and fitting this cover over theworm retaining knob 20, into engagement with the full container toshield the contents from dirt and the like as described above.

As shown in Fig. 5, the dispenser mechanism may utilize a preformedcontainer cover member 150, in which case the cover member 48 describedabove and normally supplied with a full container 10 might be discardedand would not require inclusion of a centrally located opening 50 and acooperating cap (not shown) fitted therein to protect the contents priorto use. Also, a suitable torque-applying pin 152 may be fitted throughthe retaining knob 20 as shown in Figs. 1 and 5 as an aid to applicationof sufiicient torque on the knob 20 to securely lock the latter on topof the center post 14 and also to facilitate removal of this knob aswhen removing the piston during replacement of empty containers andduring repair or other servicing operations.
